Sewer Line Repair Cost in Houston (2026): Three Real Scenarios
Ask three Houston contractors what a sewer line repair costs and you will get three numbers that do not overlap. The reason is not that one of them is lying. It is that "sewer line repair" covers a $600 jetting job and a $25,000 tunnel under a kitchen, and nobody can tell which one you have until a camera has been down the pipe. So instead of a single range, here are three houses we see every month and what each one actually costs in 2026.
First, the numbers that apply to every job
| Item | Typical Houston price |
|---|---|
| Camera inspection with recording | $250 – $500 |
| Hydrostatic test (slab homes) | $250 – $500 |
| Hydro jetting the main line | $350 – $900 |
| Adding a cleanout | $600 – $1,500 |
| City of Houston plumbing permit | $100 – $300 |
The camera is the only one you cannot skip. A contractor who quotes a repair without one is quoting what they imagine, and a contractor who ran one and will not show you the video is asking you to pay for a description. Typical ranges throughout, not a quote.
Scenario one: the Westbury offset
A 1972 one-story in Westbury, ABS lateral, 45 feet from the cleanout to the property line, 3 feet deep, grass on top. The downstairs tub backs up every few months and has been snaked twice. The camera shows one joint offset by two inches at 22 feet, with hair roots from a water oak, and sound pipe on both sides.
That is a spot repair. One 4-by-6-foot hole, the bad coupling cut out, new schedule 40 PVC on proper couplings, bedded on sand at a quarter inch per foot of fall, inspected, backfilled, sod replaced.
- Camera and locate: $350
- Spot repair with permit: $1,800–$2,600
- Sod and sprinkler repair: $150–$300
About $2,500–$3,200, one day. If the joint had been under the driveway, the concrete cut and re-pour adds $1,000–$2,000 and a second day.
Scenario two: the Katy lateral
A 1994 two-story in Cinco Ranch, PVC lateral, 60 feet, 4 feet deep, crossing the front walk. Backups after every heavy rain and a slow line between. The camera shows offsets at four joints and a 12-foot belly holding water where the lot was filled during construction. There is no single spot to fix.
That is a replacement, and there are two ways to do it.
Open trench. Dig the 60 feet, cut and re-pour the 4-foot walk, new PVC on sand bedding at correct fall, inspect, backfill, sod. $6,500–$10,000, two to three days. The belly is gone because the pipe is re-bedded.
Trenchless. Because there is a belly, lining is out — a liner follows the sag. Pipe bursting would pull new HDPE through and could work, but it does not fix a belly either. So on this house, open trench is the right answer and the cheaper one, and a trenchless quote of $12,000 is the wrong tool sold well. Lining vs. pipe bursting explains when the reverse is true.
Scenario three: the Meyerland slab
A 1961 one-story in Meyerland, cast iron throughout, leveled by a foundation company last month. Their hydrostatic test failed. Isolation testing narrows the leak to the run serving the hall bath, and the camera finds a separated hub 16 feet in from the east grade beam.
That is under-slab work, and this is where quotes spread furthest apart.
- Tunnel to the hub: 16 feet at $150–$250 per foot plus the plumbing, a permit, an inspection and a second hydrostatic test. $5,000–$8,500, three days.
- Overhead reroute of the hall bath: abandon the cast iron, run new drains through the attic and down the exterior wall. $8,000–$12,000, plus drywall. Worth it only if the rest of the cast iron under the house is also failing, which the camera will show.
- Whole-house tunnel replacing all the cast iron under the slab: $20,000–$30,000. This is the number some homeowners are quoted for scenario three, and it is the right job for a house where the camera shows channel rot everywhere, and the wrong one for a single failed hub.
The under-slab page goes through how we choose, and under-slab sewer repair on Houston homes walks the decision on a real floor plan.
What moves every one of these numbers
- Depth. Most Houston laterals are 2–5 feet down. Every foot deeper adds shoring, spoil and time.
- What is on top. Grass is nearly free to restore. Concrete is $1,000–$4,000. A live oak's root zone or a pool deck means trenchless or nothing.
- A cleanout. Without one, every inspection starts with a pulled toilet. Add it once.
- Restoration. Sod, sprinklers, concrete and landscaping should be on the estimate, not the invoice.
- The license. Sewer work in Texas is plumbing, and the City of Houston will not issue the permit to anyone but a licensed Responsible Master Plumber. An unpermitted job is cheaper on the day and a problem at resale.
How to compare quotes
Line them up by method. A $3,000 spot repair and a $9,000 replacement on the same house are not competing bids; they are two different diagnoses, and the camera footage decides which one is right. Ask each contractor for the video, the footage counter where the problem is, and the method. If two contractors agree on the method, their prices will usually be within 20% of each other. If they do not agree, the cheaper one has not necessarily found the better price — they may have found less of the problem. The pricing page has the full tables by method.
